From what I understand, the biggest issue was their product required fast fan out messaging. Tumblr, for example, is still huge but can get away with 1000 lines of PHP for their feed: https://news.ycombinator.com/item?id=17154403
Twitter, even back in those days would have still outgrown today's Rails. It was Ruby that has gotten a lot faster. Not necessarily Rails.
